- rare - 300 mm,
- front - 800 mm.
- floor –the fireplace must be placed on a non-combustible floor.
The manufacturer is not responsible for consequences caused by not
following the instructions.
6.2. Smoke exhaust system
The correct assembly and connection of the flue gas exhaust system is extremely
important for the trouble-free operation of the pellet stove.
The pellet stove works constantly with pressure in the flue.
It is forbidden to vent flue gases directly from the pellet stove through the wall into
the atmosphere.

8
It is mandatory to install a flue to remove flue gases at a height safe for human health
and to be equipped with wind protection.
The flue must be used only by the pellet stove and no other appliances must be connected
to it.
Flue gases are released from the combustion chamber of the pellet stove to the
atmosphere through an opening with a diameter of Ø 80 mm, located in its rear part.
If the outlet of the pellet stove is connected to a metal flue, it must have a vertical part with a
length of not less than 2.5 m, equipped with wind protection device. The pipe system must be
airtight insulated with materials resistant to high temperatures (heat-resistant silicone).
Classic masonry chimneys can be used to vent the smoke. If the pellet fireplace is
connected to a brick chimney, it must be well built and plastered (no cracks).
All parts of the flue must be freely accessible for inspection.
In the lower part of the flue there must be an inspection opening, allowing
opening and cleaning.
It is forbidden to install regulating flaps in the smoke outlet (valves that can prevent the
removal of smoke, respectively make it difficult to draft).

be necessary to isolate them from the metal flue with fireproof materials (see figure 7).
ATTENTION! Do not connect the exhaust gas system of the pellet stove to a chimney to
which another stove, boiler or aspiration system is already connected.
6.3. Combustion air supply
The air needed to burn the pellets is taken from the room where the pellet stove is
installed. It is sucked from the smoke fan through a pipe with a diameter of Ø 43 mm.
If there is another heating appliance in the room, the necessary amount of air
must be provided for the proper functioning of all appliances.
6.4. Connecting the pellet stove to the power supply
The pellet stove works with a supply voltage of 230 V / 50 Hz and therefore it must
be connected to an electrical supply.
Before connecting the pellet stove to electricity, make sure that:
•the characteristics of the electrical network correspond to the data or
specification given on the nameplate of the stove.
•The power cord must be kept away from hot places and must not come into contact
with sharp edges that could injure it.

11. Pellet quality requirements
ATTENTION! The pellet stove has been tested only with wood pellets with a diameter of 6 –8
mm, class EN plus A1, acc. EN ISO 17225-2:2014. The manufacturer accepts no responsibility
if you use fuel other than that recommended by the manufacturer.
This pellet stove is made to use pressed wood (pellets).
There are many products of this type on the market, it is important to choose pellets that
have the lowest ash content and are not too wet (always ask for a pellet test certificate
from the supplier).
The correct functioning of the pellet stove depends on the type and quality of the
pellets.
When the pellets are of low quality, the stove must be cleaned frequently.
Benefits of using pellets:
-Allow easy loading.
-Better regulation of fuel quantity.
-The small size of the pellets allows the precise supply of the fuel.
-They allow air supply to achieve optimal combustion efficiency.
The high combustion efficiency is also determined by the low moisture content in
pellets (constantly below 10% compared to 20% to 30% moisture content of sawn wood).
-Pellet bags can be stored in a small area in a dry garage, basement, utility room or
shed.
Pellets should be stored in a dry place that is not too cold. Cold and wet pellets reduce the
thermal power of the fuel and require additional cleaning of the combustion chamber .
Pellets should not be stored near the pellet stove - at least 2 meters away from it. Do not
crush them.
The manufacturer of the stove is not responsible for the use of wood pellets with poor
quality, nor for the poor performance of the pellet stove due to such fuel.
12. Information relating to dismantling and destruction of the stove
Dismantling, disposal and destruction of old, used stoves is the responsibility of the owner.
The owner of the stove must comply with all legal regulations of his country and the
European Union regarding safety and environmental protection.
The dismantling and storage of materials from the stove can be entrusted to a third party
authorized to collect and dispose of these materials
